Subaru will be represented by Subaru Tecnica International (STI) at this year's 24-hour of Nurburgring race. Rolling in their new and improved 2011 WRX STI "ts", the STI team has been very busy testing and tuning in order to compete in the SP3t class. Most recently the STI NBR Challenge 2011, the nickname for the race car, did some testing out at Fuji Speedway.

The car will be powered by a 2.0 Boxer DOHC with a twin scroll turbo pushing out 335-hp and 340 ft-lbs of torque. It'll be mated to a 6-speed transmission with a front, center and rear LSD. Suspension will be handled by Bilstein while it'll race on Dunlop tires wrapped around BBS wheels.

Obviously a huge collection of STI products will be on the race car, from clutch and flywheel to trunk spoiler and drive shaft.
